Specification of Letters Patent.

Patented April 23,1907;

Application filedliovember 24, 1906. Seria No. 288,827.

To all whom it may concern.-

"Be it known that I, Mosns NEIBURGER, a citizen of the United States, residing at La Fayette, in the county of Tippecanoe and "State 'of Indiana, have invented new and useful Improvements in Nut-Locks and I do declare thefollowing to be a full, clear, and exact descrlptlon of the invention, reference being had to the accompanying drawings, and.-

to the letters and figures of reference marked thereon, which form part of this specifica hicles or vibrating articles such as rail-joints,

the invention having reference particularly to nut-locks of the washer type, and to bolts and other articles that are adapted to hold the washers to enable the washers to hold the nuts.

Objects of the invention are to provide nut-locks that willbe neat in appearance and suitable for use onhigh-speed machines and those which may be well-finished to provide nut-locks that maybe adapted to be used in many situations, that may be cheaply produced and'be durable and economical in use.

WVith the above mentioned and minor objects in view, the invention consists in a washer having projections at one side thereof for holding thewasher, and having also fingers extending from the peripheral edge thereof adapted to be bent up to hold a nut, and a bolt or other element having recesses to receive the projections of the washer; and the invention consists further in the parts and combinations and arrangements of parts, as hereinafter particularly described and claimed.

Referringto the drawings, Figure 1 reprethe washer and integral arts thereof; Fig. 3,

ings designate correspondingelements or feetures.

In a practical embodiment of 'the inven tion, a washer B is provided, preferably'coin' posed of sheet steel, andit has 'a circular hole L o of suitable diameter to receive the threaded end of a bolt. The washer is provided with a pair of projections C and C ateither side of the hole that are formed integrallyof the metal of the washer, the projections being at one side of the washer and designed'tobe placed in recesses to prevent rotationzof the washer about a bolt. The washer has a num. ber of integral fingers, preferably six, as b,.c, (l, 6,)", g, that extend from the periphery thereof, each fingcrbeing broader near'its 'eX- treinity than .at its base or part that is at tached to the washer, and is adapted'to'be' bent up against a flat sideof a nut that may be seated on the washer. The side of the washer opposite to that having the projec tions has s ight grooves h extending into the projections which are each formed of two thicknesses of the metal sheet forming the washer. i

Another part of the nut-lock comprises a bolt D having a pair of recessesi and i at opposite sides thereof that are out or pressed into a shoulder j which is formed at the end of the body part of the bolt, there being a bolt end extending beyond the shoulder that has screw-threads 7r thereon, the washer being seated on the shoulder with the projections C and C in the recesses i and i, and a nut E is placed on the threaded end of the bolt and is seated on the washer to hold the bolt in elements as X and Y, the bolt in such cases being adapted for use as a removable pivot, or for merely holding a number of elements together, as may be desired.

In order to produce the Washer and integral parts thereof, a plate F is stamped out of a sheet of metal, and an oblon hole G is" punched in the plate, the plate be ng oblong in plan, and in the longer edges thereof are two notches m and m having straight bottoms n and n. either side of the major axis of the plate, are

V-shape notches 0, p, q, 1", the parts of the In the shorter edges at Suitable formers and dies are em- IIO fiat side of the nut opposite a finger of the shoulder from which extends a screw-threadwasher, either one of the fingers being then turned up against a fiat side of the nut to prevent the nut from unscrewing accidentally. To remove the nut, the finger may be a ain straightened, and when a finger breaks 0 from repeated bending, another finger may be used.

Having thus described the invention, what is claimed as new is l 1. Anut-lock including a bolt having a 'ed'end and provided with a pair of recesses in the-shoulder adjacent to the screw-threaded end, a notched washer plate having parts ther of insertible in the recesses of the shoulder, and a nut to receive the threaded end and hold the parts of the washer plate in the recesses, said nut adapted to be locked by other parts of the washer plate.

2. A nut-lock comprising an element having a shoulder provided with two separate recesses, a threaded bolt-end havlng connecserene 3. A nut-lock including a bolt having a shoulder from which extends a screw-threaded end and provided with a pair of recesses in the shoulder adjacent to the screw-threaded end, in combination with a washer having a pair of projections insertible into the recesses ofthe shoulder and having also a plurality of fingers on the periphery of the washer.

t. A nut-lock washer formed of a blank com prising an oblong plate having an oblong hole therein and having notches in the peripherv thereof, two oi the notches being broader than theothers, and the body of the washer being of uniform width between the hole and the bottoms or inner ends of the notches.

In testimony whereof, I afiix my signature in presence of two witnesses.
